Application ii1ed Ann 14,

This invention relates primarily to tiles and tile arches employedint'he construction of tunnel kilns, but is not limited in itsapplication to such use; Among the objects oi our invention are; toprovide new and improved tile for the construction or tile arches; toprovide a new construction of tile arch to provide improved ine'a'nsforperinitting enpai'ision and contraction of the tiles in tile arches,without placing strain on the tiles; and such turtl'i'er objectsadvantages and capabilities as will later more fully appear. A

Gu invention further resides in the coinbination, construction anda-rrai'igenie'nt of parts illustrated in the accoinpa'i' y'ing drawingsand while we haveshown therein preferred en'ibodinients we desire thesame to be understood as ilhistrative only and not as limiting ourinvention.

in the accompanying drawil'igs, Fig. l is an end view of one torin attile eniboc'lying our present invention; Figs. 2 8 and 4 are crosssections of tile arches constructe'd ii-i accordance with our presentinvention; Fig. is an 15011165110 cross section of a tile arch supportedby structural steel; Fig. 6 is an isometric View of a tile such as thatshown in Fig. 1, and 7 is a fragmentary section showing a modified formof tile having spacing ridges, lugs, 01' the like, on the projectingflanges, to cause spacing of the tiles and reduce friction tending toprevent the tiles from sliding with respect to one another when heated.

Referring more in detail to the annexed drawings, numerals 1, 2, 3 and 4designate tour ditlerent tiles embraced in our invention, those shown inFigs. 1 6 and 7 being hollow, while those shown in Figs. 2; 3, 1 and 5are solid. It will be obvious from Figs. 1 6 and 7 that the hollow tilesmay be formed with longitudinal apertures of any desired shape, such ascircular, square or oblong in cross section, but. as shown in thesefigures, it is preferable that there be a central aperture 5, extendingsubstantially across the tiles. Between the ends of this aperture 5 andthe side walls of the tile are slits 6 which weaken these walls of thetile so that it can be readily broken in two by being suitably struck.This will result in the formation of half tiles, which may be used inthe same manner as tiles 3 in Figures 2 to 5; The tiles t are formed insubserjiai no; 4613469;

lly the same manner is the titles 1, are provided at certain edges withY es, Inge, or the like, 7. These result in the production of air spacesl'JetWeen the tiles wlie'ii' they are built into a construction as shownin F T. suit in th'edecrcase in the amount of friction between engagingspaces and therefore make it easier for them to slide on each other whenthe tile arch isheated during use. Vith the constructions shown in F 12, this result is in part accomplished in a (litter-silt manner, thatis, by inserting betw en the tiles, at the points marked 8 strips pl orthe like. Wlren the kiln is heate ese strips oit aper will burn out l'e""e spaces between the tiles to z'rccoh'rni'oda'te the expansion due toheating oi the tiles I The various forms of construction an: the tilearch will next be desc 'ibed. Fig. 2 shows the construction of a tilearch C0111- prisin'g whole tiles 2 and half tiles 3 supported byconcrete 9 having ei'n'bedded therein reii'i' torci'n'g rods 10'. Itwill be obvious that when this construction has' been erected and hasbecome thoroughly set, if a fire is started and the kiln is heated to ahigh tentperfre, the paper or the like at 8 will be burned out and. willleave a slight space at these pointstoi the necessary relativeinoveinent caused the expansion and contra-cti'o'n oi the tiles whenheating up and cooling d r'iw'n'. v

The construction of Fig. 3 is siinilar to that of Fig. 2 but hassupporting I-beanis, portions of which are embedded in the concrete 9.Connecting the I-beams 11 are tie rods 12 which are embedded in theconcrete 9 and hold the I-beanis in position. This figure also shows theuse of an ext layer of tiles 2 to increase the thickness of the kilnstructure.

In Fig. 1 a plurality of reinforced concrete girders take the place ofthe I-beams 11 shown in Fig. 3 and these are stayed by cross beams 14which take the places of the tie-rods 12 of Fig. 3. It will be noticedthat in this figure the thickness of the tiling is midway between thethicknesses shown in Figs. 2 and 3. The til-es 2 and 3, the paper stripsin spaces 8, the concrete 9 and the reinforcing rods 10 are the same inthis figure as in the preceding figures.

In Fig. 5, I-beams 11 support channel irons These projections also re-Ms will be sup- 0 second named and held braced so 111.1%" th M 1011. n.\JIZHUN. PY (E. LYVKETT.
